This article mainly explains "how to install tensorflow under mac". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn how to install tensorflow under mac.

Installation: 1. Install virtualenv use the pip command to install vmac$ sudo pip install-- upgrade virtualenv 2. After installation, I created a working directory, and I created a folder directly in home. Vmac$ virtualenv-- system-site-packages ~ / tensorflow 3. Then enter the directory to activate the sandbox vmac$ cd ~ / tensorflow vmac$ source bin/activate (tensorflow) vmac$ 4. Download tensorflow http://pan.baidu.com/s/1ntjaMnf password: sznb puts the downloaded tensorflow-0.5.0-py2-none-any.whl file in the ~ / tensorflow directory. After entering the sandbox, execute the command to install tensorflow in the sandbox. (tensorflow) vmac$ pip install-- upgrade tensorflow-0.5.0-py2-none-any.whl

5. Create a myfirst.py file to test it. Vmac$ python myfirst.pyimport tensorflow as tfimport numpy as np# Create 100 phony x, y data points in NumPy, y = x * 0.1 + 0.3x_data = np.random.rand (100) .astype (np.float32) y_data = x_data * 0.1 + 0.1 Try to find values for W and b that compute y_data = W * x_data + b # (We know that W should be 0.1 and b 0.3 But Tensorflow will# figure that out for us.) W = tf.Variable (tf.random_uniform ([1],-1.0,1.0)) b = tf.Variable (tf.zeros ([1])) y = W * x_data + b # Minimize the mean squared errors.loss = tf.reduce_mean (tf.square (y-y_data)) optimizer = tf.train.GradientDescentOptimizer (0.5) train = optimizer.minimize (loss) # Before starting, initialize the variables. We will 'run' this first.init = tf.initialize_all_variables () # Launch the graph.sess = tf.Session () sess.run (init) # Fit the line.for step in range: sess.run (train) if step% 20 = 0: print (step, sess.run (W), sess.run (b)) # Learns best fit is W: [0.1], b: [0.3] Thank you for reading The above is the content of "how to install tensorflow under mac". After the study of this article, I believe you have a deeper understanding of how to install tensorflow under mac, and the specific use needs to be verified in practice.
